15.10.2
Register Name:
Access Type:
Reset Value:
• VECTOR: Interrupt Handler Address
The user may store in these registers the addresses of the corresponding handler for each interrupt source.
15.10.3
Register Name:
Access Type:
Reset Value:
Offset:
• IRQV: Interrupt Vector Register
The IRQ Vector Register contains the vector programmed by the user in the Source Vector Register corresponding to the
current interrupt.
The Source Vector Register (1 to 31) is indexed using the current interrupt number when the Interrupt Vector Register is
read.
When there is no current interrupt, the IRQ Vector Register reads 0.
